'A' purchased an article and sold it to 'B' at 10% profit. 'B' marked it up by 18% above the price at which 'A' has purchased it and then sold it after giving a discount of Rs. 490. If 'B' suffered a loss of 15% in the transaction, then find the cost price of the article for 'A'.
Let the cost price of the article for A be Rs. x Therefore, cost price of the article for B = Rs. 1.1x Marked price of the article = Rs. 1.18x Selling price of the article for B = 0.85 × 1.1x = Rs. 0.935x According to the question, 1.18x – 0.935x = 490 Or, x = 490/0.245 = 2000 Therefore, cost price of the article for A = Rs. 2000
